Mucocutaneous presentations of Crohn's disease

Crohn's disease is an idiopathic inflammatory process that predominantly affects the gastrointestinal tract. Numerous extraintestinal manifestations of Crohn's disease involving the skin and mucous membranes have been reported in patients with documented intestinal disease. We report here on two patients who presented with multiple manifestations of Crohn's disease before intestinal disease was diagnosed. We review the mucocutaneous manifestations of Crohn's disease with an emphasis on presentations that precede gastrointestinal involvement.
